150t = 600 Simplify
t = 4 Divide
70(4) + 80(4) = 600 Check
4 hours
Answer:
Parallel to line a: y=3x-2
Perpendicular: y= -1/3x-2
Neither: y=1/3x+1
Step-by-step explanation:
Parallel means that they have the same slope, which is 3x in line a. So y=3x-2 has the same slope as line a. Perpendicular means that it has the negative reciprocal, which of line a would be y= -1/3x-10. The remaining equation is for the last box, which is neither parallel or perpendicular.
Answer:
9.5ft/min
Step-by-step explanation:
find the common difference between the numbers and divide if by the time.
in this case:
73.5-64=9.5
and the time is in one minute
so:
9.5/1
